Here's my solution for that stupid hw08

Updated h08.cpp

#define STR_REL temp << "data set " << set << ": total values = " << sum << \
	"\naverage value = " << fixed << setprecision(4) << total / sum <<

std::string dataSets(const std::string& fileName) {
  double total = 0, mul;
  int real = 0, set = 1, sum = 0;
  ifstream istrm;
  istrm.open(fileName);

  ostringstream temp;

  if (istrm.fail()) {
    cout << "Failed to open " << fileName << '\n';
    return fileName + " cannot be opened.";
  }

  istrm >> real >> mul;
  if (istrm) {
    do {
      if (real == 0) {
        real = static_cast<int>(mul);
        istrm >> mul;
        STR_REL "\n\n";
        sum = 0;
        total = 0;
        set++;
      }
      sum += real;
      total += real * mul;
    } while (istrm >> real >> mul);
    STR_REL "\n";
  }
  istrm.close();
  return temp.str();
}
